Hi,
I've been hunting a memory error in publish handling the last couple
of days.
The error is on our old but good 3.1.x presence server.
Using memory debug, I located the memory leak in
modules/presence/hash.c, function insert_phtable, line 492 (in trunk):
p= (pres_entry_t*)shm_malloc(size);
As far I can see there are two errors when deleting publish htable entries
1. When calling delete_phtable pres.event->type is used instead of
pres.event->evp->type
2. When creating publish hashtable, p->publ_count is not set.
(defaults to 0)
In delete_phtable, the following code is present
p->publ_count--;
if(p->publ_count== 0)
p->publ_count is probably decremented to -1 (unless the user have two
active dialogs)
I attach a patch, which I would carefully test in a test environment :-)
Regards,
Kristian Høgh

Hello all.
I'm consistently watching a memory increase
in kamailio when dealing
with
PRESENCE events, namely SIP PUBLISH events. The
system eventually hangs
running out of memory.
This behavior is seen at least in kamailio 4.1
and 4.2. I'm
currently using
the latest stable 4.2.2.
If I disable the SIP PUBLISH handling in kamailio
i don't observe
the issue
anymore but as a side effect I don't have
presence (name BLFs) also.
What do you think can be the right approach here?
Should I open an
issue in
github for this? Should I run kamailio under
valgrind for some time? Are
there any other possible debug hints here?
Please find attached a code snippet with the
presence related parts I'm
using right now.
Looking forward to hear from you.
Best Regards,
